For as long as there have been humans in the Central Valley grasslands, they have hunted, fished, and gathered plant or animal life for consumption. “Foraging” became a health concern with the evidence of selenium accumulation at Kesterson Reservoir. A survey suggests that a large number and variety of people forage. The amounts and frequency of consumption are probably not great enough to be a health hazard to any one person or group, but there is still some cause for concern.
